The outtake for 無限宝くじ7
Strengths to defend, gaps to attack

- Lack of social or competitive features
- Limited to one lottery format (7/37)

Market Threats

What are the next best moves?
Analyze conversion and retention metrics following the transition to the $2.99 paid model.
The recent shift from ad-supported to paid (v1.4) is a major strategic pivot that directly impacts user acquisition and revenue.
Expand simulation variety beyond the current 7-number format to include other popular lottery types.
The app description currently only mentions a 7/37 format, which limits the addressable market of lottery enthusiasts.
Introduce a 'Statistical Dashboard' showing cumulative simulated spending vs. winnings.
Adding data visualization would provide more value for the $2.99 price tag and lean into the 'simulation' aspect described in the app metadata.
Key Takeaways
If I were the PM of this app, I would focus on justifying the $2.99 price tag by adding more simulation depth, such as 'what-if' financial scenarios or historical data tracking. While the ad-free stance is a strong differentiator, the current feature set is too narrow to sustain long-term interest in a paid-only model without further expansion into other lottery formats.
Where Is It Heading?
Stable
v1.4 update (Oct 2025) maintained the app over a year after release — active maintenance but no new features.
Transitioned to paid model to remove ads — strategic shift to prioritize UX over volume.
